Cooperly vs Windmill
Cooperly is for founder-led companies that need the work fixed while it is still moving. Windmill’s agent, Windy, gathers work data all year so reviews are mostly drafted before the cycle; Cooperly turns the same kind of signals into an owner and an agreement this week.

Old rule
Collect a year of evidence to write a better review.
New rule
Use the evidence while the handoff can still be fixed.
A review drafted from twelve months of Slack and Jira is faster, but it still arrives after the missed deadline. Cooperly shows the founder which decision has no owner today, so the team settles it before anyone needs to be reviewed for it.
Read what the work already shows
Decisions, commitments and blockers already sit in Slack channels, ClickUp chat and Asana tasks. Cooperly proposes them as team facts; the team lead confirms each one.
Ask only what tools can’t tell
Profiles, Pulse and Fundamentals add how people work, what feels stuck and which agreement needs another conversation.
Your agents prepare. People decide.
ChatGPT, Claude and your other approved tools read the picture through MCP. The team agrees the owner and the next step.
Windmill vs Cooperly: features and fit
Cooperly is built for founder-led companies before management becomes an HR programme. Compare that job with the one Windmill is designed to do.
| Dimension | Cooperly | Windmill |
|---|---|---|
| What the work data is for | Finding the decision without an owner, the commitment that slipped and the blocker between two people. | Feeds reviews, 1:1 agendas and calibration. Cooperly uses work context to settle ownership while the work is still open. |
| Who acts on it | The team lead confirms each proposed fact; the team agrees the owner and next step. | Windy messages people in Slack to collect feedback and drafts reviews for managers to edit. Cooperly does not act for anyone; it gives people and their own AI tools the confirmed team picture. |
| Sources | Slack channels, ClickUp chat and Asana task text, plus meeting notes and retros you add. | Lists 35+ integrations including Slack, GitHub, Jira, Linear, Notion, calendars and meeting recorders. Cooperly reads fewer sources and asks a lead to confirm each fact before it counts. |
| What people add | Coop Profiles, Pulse and Fundamentals: how people work, what feels stuck and which agreement needs a conversation. | Collects self, peer, upward and manager reviews plus pulse surveys. Cooperly asks people only what work tools cannot show and uses the answers to prepare the next conversation. |
| Performance reviews | Not a review system. Cooperly works on the cause before it becomes a review finding. | Runs review cycles and calibration with AI drafts. Cooperly is the better fit when you would rather have fewer things to review. |
| AI access | MCP for ChatGPT, Claude and other approved clients. Read-only by default; Claude and Codex can write after the person confirms a preview. | Publishes an MCP server that reads and writes reviews, 1:1s, pulses and feedback. Cooperly’s MCP carries team facts, profiles and agreements. |
| Founder view | Overview shows where work still depends on the founder or one key person, team by team. | Analytics follow review, feedback and pulse data. Cooperly shows the owner where the company still routes through them. |
| HR records | Keeps the HRIS where it is; Cooperly holds the working context. | Connects to HRIS systems such as Rippling, BambooHR and HiBob for review cycles. Cooperly needs no HRIS to start. |
| Price shape | Flat team-size price: £240/year up to 10 people, £948/year for 11–50. | First 10 users free, then $12 per user each month. Cooperly’s price does not move with each hire inside a plan. |

Why choose Cooperly as a Windmill alternative?
Start with the job you need the system to do.
Same signals, different deadline.
Cooperly reads the thread where two leads both assumed the other would ship the fix. The lead confirms it as a blocker, and the team names an owner the same week.
Windmill says most of a review is drafted before the cycle begins, because Windy has gathered the year’s work. The handoff in that review still failed months earlier; Cooperly is built to catch it the week it happens. Source for Same signals, different deadline.
Choose Cooperly when you want ownership problems settled while the work is open. Choose Windmill when you keep formal reviews and want them drafted from work data.
An agent of your own, or a vendor’s agent?
Cooperly does not add another assistant to Slack. ChatGPT, Claude or Codex reads the confirmed team picture through MCP, and the founder or lead decides what to do with it.
Windy is Windmill’s own agent: it messages people, collects feedback and prepares reviews, and Windmill’s MCP lets other clients reach the same review data. Cooperly keeps judgement with people and lets them use the AI they already pay for. Source for An agent of your own, or a vendor’s agent?
Choose Cooperly when people should keep the judgement and their own AI tools. Choose Windmill when you want an agent to run the review workflow for managers.
A customer bug that both teams thought the other had.
A customer bug sat for nine days because Product and Engineering each assumed the other had it. Cooperly surfaces the commitment from the Slack thread, the lead confirms it, and the team names one owner before the next release.
- Reach 70% AI-assisted coding across the team by the end of the year.
- Grow the messaging product's monthly revenue every month this year.
The overview measured the risk against these goals. Changed goals go into the next overview.
Decisions and priorities still flow through too few people. Adrian Cole and Serena Holt still settle most priorities and package the final feedback, so work waits for them.

Use Cooperly with ClaudeCooperly does not act for anyone. It proposes facts, sends reminders and keeps the picture current; people decide the owner and the next step. That is the main difference from an agent that runs a workflow on a manager's behalf.
